:I don't think my fix for this issue is ready for prime time. I get chimneys of essentially unscavenged SO2 extending into the UTLS during Asian monsoon, leading to too much sulfate aloft. I think replacing the instantaneous titration of H2O2 in the standard code with the correct oxidation of SO2 by H2O2 (and O3?) is necessary.

Revision as of 16:13, 7 November 2016

On this page we list the current priorities for GEOS-Chem development. This list was compiled by the user Working Groups at the last International GEOS-Chem Meeting (IGC7) in May 2015 and has been continuously updated since based on code readiness and input from the Working Groups and the Steering Committee.

We also invite you to view our GEOS-Chem Support Team project management board on Trello.com, which shows the current GCST workflow.

List of priorities as of Nov 2016

The items listed below are in different stages of readiness and will be included in future versions of the model.

Awaiting release

Items awaiting release will be part of the next version release of GEOS-Chem and are actively being incorporated into the standard model and benchmarked. More information on those items can be obtained on the GEOS-Chem v11-01 wiki page.
